7 EQ EQ Caution Item Examples Power Supply Do not impose an excessive voltage on the EQ, otherwise it may explode or burn. Do not impose AC voltage on any EQ DC model, otherwise it may explode or burn. Do not connect the AC types without load to the power supply. The sensor will be damaged. Sensor ~ Correct Use Installation Power Reset Time The Proximity Sensor is ready to operate within 00 ms after power is supplied. If power supplies are connected to the Proximity Sensor and load respectively, be sure to supply power to the Proximity Sensor before supplying power to the load. Power OFF The Proximity Sensor may output a pulse signal when it is turned off. Therefore, it is recommended to turn off the load before turning off the Proximity Sensor. Power Supply Transformer When using a DC power supply, make sure that the DC power supply has an insulated transformer. Do not use a DC power supply with an auto-transformer. Sensing Object Metal Coating: The sensing distance of the Proximity Sensor vary with the metal coating on sensing objects. Wiring High-tension Lines Wiring through Metal Conduit If there is a power or high-tension line near the cable of the Proximity Sensor, wire the cable through an independent metal conduit to prevent against Proximity Sensor damage or malfunctioning. 7

8 EQ EQ Mounting The Proximity Sensor must not be subjected to excessive shock with a hammer when it is installed, otherwise the Proximity Sensor may be damaged or lose the water-resistivity. Environment Water-resistivity Do not use the Proximity Sensor underwater, outdoors or in the rain. Operating Environment Be sure to use the Proximity Sensor within operating ambient temperature range and do not use the Proximity Sensor outdoors so that its reliability and life expectancy can be maintained. Although the Proximity Sensor is water resistive, a cover to protect the Proximity Sensor from water or soluble machining oil is recommended so that its reliability and life expectancy can be maintained. Do not use the Proximity Sensor in an environment with chemical gas (e. g., strong alkaline or acid gases including nitric, chromic, and concentrated sulfuric acid gases). DC Type Connection type AND (serial connection) OR (parallel connection) Method Description The Sensors connected together must satisfy the following conditions: i L + (N-1) x i Upper-limit of control output of each Sensor V S - N x V R operating voltage N = No. of Sensors V R = Residual voltage of each Sensor V S = Supply voltage i = Current consumption of the Sensor i L = current If the MY Relay, which operate at 4 VDC, is used as a load for example, a maximum of two Proximity Sensors can be connected to the load. A minimum of three Sensors with current outputs can be connected in parallel. The number of Sensors connected in parallel varies with the Proximity Sensor model. 8

9 EQ EQ AC Type Connection type AND (serial connection) Method Description If 100 or 00 VAC is imposed on the Proximity Sensors, V L (i.e., the voltage imposed on the load) will be obtained from the following. V L =V S - (residual voltage x no. of Proximity Sensors) (V) Therefore, if V L is lower than the load operating voltage, the load will not operate. A maximum of three Proximity Sensors can be connected in series provided that the supply voltage is 100 V minimum. OR (parallel connection) In principle, more than two Proximity Sensors cannot be connected in parallel. Provided that Proximity Sensor A does not operate with Proximity Sensor B simultaneously and there is no need to keep the load operating continuously, the Proximity Sensors can be connected in parallel. In this case, however, due to the total leakage current of the Proximity Sensors, the load may not reset properly. It is not possible to keep the load operating continuously with Proximity Sensors A and B in simultaneous operation to sense sensing objects due to the following reason. When Proximity Sensor A is ON, the voltage imposed on Proximity Sensor A will drop to approximately 10 V and the load current flows into Proximity Sensor A, and when one of the sensing objects is close to Proximity Sensor B, Proximity Sensor B will not operate because the voltage imposed on Proximity Sensor B is 10 V, which is too low. When Proximity Sensor A is OFF, the voltage imposed on Proximity Sensor B will reach the supply voltage and Proximity Sensor B will be ON. Then, Proximity Sensor A as well as Proximity Sensor B will be OFF for approximately 10 ms, which resets the load for an instant. To prevent the instantaneous resetting of the load, use a relay as shown on the left.
